l the ineitin of the fuse to project a stream of oil (or whatever fluid the fuse is immcrset in) across the fuse terminals, so as to quickly extinguish the arc.

The invention consists of the combination with a suitable vessel, or receptacle for the oil or other fluid, of a'baille plate therein, fuse terminals on one side of said battle, and a fuse attached to said terminals and led through holes in said barrier.. When the fuse blows,- the oil is expelled through said holes in streams which quickly cut off the arc.

In the accompanying drawing, Figure l is a vertical longitudinal section of a structure embodying my invention; Fig. 2 is a vertical cross section of the same on the line 2--2, Fig. l; and Fig. 3 is a top plan view with the lid removed.

-ihe vessel, receptacle or tank 1 isof any suitable material, preferably cast iron. It has a lining 2 of insulating material, and is provided with a lid 3-held down by yield ing fastening-s, such, for instance, as the hinged bolts 4, thumb nuts 5 and the springs 3 interposed between said nuts and the lid.

On the bottom of the tank rests a-base plat T preferably of wood, on which are mounted the clipsS to which are connected the insulated conductors i) which pass out thrmigh the walls of the tank near its top. (in the base plate are two upright transverse partitions ll), located between the terminal clips On these partitions rests a horizontal balile plate 1l,Wll0 1U edges are adjacent to the walls of the tank; being cut away at two corners to permitthe conductors 9 to pass by it. At each end of the barrier is an upright wall 12, and its middle an upright partition 13. A top bar 1% rests on the walls 12 and the partition 13. in the battle plate are four openings, those nunr bored 15 being above the clips and those the expansion of the produced by numbered 16 being between each partition 10 and middle partition 13. Resting" on the battle plate above each hole Ii 5 is a. block 17 to which secured a blade 18 passing down through said hole into the clip 8 below. The block .rries a bindin g screw 19 by means of which one end oi the fuse 20 is fastened ll'iereto. ise depends through the holes 16: the big'ht l A in he chan'iber 21 fora.

l0 and the battle plate.

The iid,3 provide n its under surface with depending; lugs which engage the upper surface of the top bar 14, so that the closing-of the lid operates to clamp the balllc plate ll firmly in position againstthe expulsive action. of the fuse at the time of disrup tion. The springs 6, which bear down upon the top of the lid, act as a yieldablc means to permit the air and gases within the box to escape upon excessive rise in pressure thereof. Y

The operation is as follows: T he parts he in;- in the position-shown, if the fuse blows,

the expanding gases force the oil from the chamber 21 up through the holes 16, and

these streams of oil shooting past the bindin screws quickly cut off the are at these points and extinguish it. i

lVhile I have shown and described the ballie plate as being arranged horizontally,

.with the fuse depending below it, yet it is evident that this arrangement is not essential, and that other. modes of carrying out the invention are possible.

What I claim as new, and desire to secure by Letters Patent of the United States, is,-

1. A fuse submerged in liquid, and llltillls for directing the liquid in astrcani past the fuscends upon blowing of the fuse.

2. A fuse submerged in liquid, and in vans for causing the gases produced by theblowing of the fuse to force the liquid to stream past the fuse ends.

The combination with a tank, aliquid therein, a fuse sulnnerged in saidliquid, a battle plate in said tank below the surface of the liquid and interposed betw 3n the fuse termina and the body of the fuse. 4

at. he combination with a. tank, liquid therein, a. fuse submerged. in said liquid, and a baffle plate having holes through which said'fuse passes adjacent its terminals.

5. The combination with a tank, liquid therein, a submerged bafiie plate havingholes, fuse terminals on one side of said merged fuse'tlierein, a base plate, upright plate, and a fuse located mainly on the other partitions thereon, and a hafiie plate resting side of said plate and having its ends passed through said holes and. attached to said terminals.

6. The combination with a tank, liquid therein, a fuse submerged in said liquid, and

:1 baffle plate dividing said tank beneath the surface of the liquid and provided with apertures through which the fuse passes to its terminals.

7. The combination with a tank, of a subon said partitions and having holes through 15 which said fuse depends into the space between said partitions.

In Witness whereof I have hereunto set my hand-this 2nd day of May, 1905.

CHARLES E. EVELETH.
